Description

Be used for paralysed patient to shift and nursing device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a transfer and nursing device for paralyzed patients.

Background

Paralysis is a decrease or loss of voluntary motor function, a common symptom of the nervous system, and is caused by a disease of the nerves, neuromuscular junctions, or muscles. Paralyzed patients cannot move limbs due to high spinal cord injury and have no intuition. Therefore, when a paralyzed patient is moved, the patient needs to be transported conveniently by an auxiliary device. The existing hoisting and transferring device for the high paralyzed patient has the following disadvantages in use:

1. after a patient is hoisted by the conventional hoisting device, the patient is directly driven by a motor, and the hoisting height is kept, so that the motor is acted by force for a long time to generate a certain load on the motor, and meanwhile, the hoisted patient is unstable and may fall off due to the fact that the motor cannot bear the load;

2. the existing hoisting is carried out by using a rope, and after the hoisting is carried out, a hoisted patient can shake under the action of the rope in the transferring process, so that the instability is caused, and accidents are easy to happen;

3. the existing hoisting needs to manually carry the patient to a hoisting plate, which is troublesome and may cause injury to the patient.
